Here is an updated ebuild for EAPI 7, CPU_FLAGS_PPC, and it fixes enabling SSE2 support. It could probably be keyworded for ppc/ppc64 since it explicitly supports it, but it no longer compiles with AltiVec since modern GCC seem to be more strict about intrinsics usage, so cpu_flags_ppc_altivec should be masked for that.

This also drops the explicit int size specification for amd64/x86 since these values are automatically determined, and they apply for other architectures as well. (It computes the size of long for the default option, and this value is cached in a CONFIG_SITE file with crossdev, so it works everywhere.)

altivec patch from buildroot: https://github.com/buildroot/buildroot/blob/master/package/libdvbcsa/0001-altivec-powerpc64.patch adding it + passing -flax-verctor-conversions fixes build but only on big-endian ppc64 and ppc32 ppc64le test failures look like classic endianess problem. so I masked there.
